/**
 * Creates nodes
 * <b>
 * The purpose of this class is to decouple the creation of
 * a class of type "Node" from its actual implementation.  This
 * class should be used instead of calling the constructor
 * of an implementation of "Node"
 * (at the moment "SimpleNode") as it may change in the future.</b><p>
 *
 * Other plans: add features here to recyle old nodes rather than
 * leaving them to the Java garbage collector
